  2. Microwave power meter - Wikipedia

    en.wikipedia.org/wiki/Microwave_power_meter

    A microwave power meter is an instrument which measures the electrical power at microwave frequencies typically in the range 100 MHz to 40 GHz. Usually a microwave power meter will consist of a measuring head which contains the actual power sensing element, connected via a cable to the meter proper, which displays the power reading.

    en.wikipedia.org/wiki/Monolithic_microwave...

    Monolithic microwave integrated circuit, or MMIC (sometimes pronounced "mimic"), is a type of integrated circuit (IC) device that operates at microwave frequencies (300 MHz to 300 GHz). These devices typically perform functions such as microwave mixing , power amplification, low-noise amplification , and high-frequency switching.

  5. Wilkinson power divider - Wikipedia

    en.wikipedia.org/wiki/Wilkinson_power_divider

    Power divider in microstrip technology. In the field of microwave engineering and circuit design, the Wilkinson Power Divider is a specific class of power divider circuit that can achieve isolation between the output ports while maintaining a matched condition on all ports.

  6. Grid dip oscillator - Wikipedia

    en.wikipedia.org/wiki/Grid_dip_oscillator

    Grid dip oscillators were first developed in the 1920s and were built with vacuum tubes.The devices displayed the amplitude of the tube's grid current, hence GDO.. Modern dip meters are solid-state devices, and are sometimes called gate dip oscillators or emitter dip oscillators in reference to the analogous part of the transistor whose current is measured instead of a vacuum tube grid.

  8. Wattmeter - Wikipedia

    en.wikipedia.org/wiki/Wattmeter

    At radio frequencies (RF) a common method is a rectifier circuit arranged to respond to current in a transmission line; the system is calibrated for the known circuit impedance. Diode detectors are either directly connected to the source, or used with a sampling system that diverts only a portion of the RF power through the detector.

  9. Frequency counter - Wikipedia

    en.wikipedia.org/wiki/Frequency_counter

    This can make a frequency reading, when referenced to the timebase, seem higher or lower than the actual value. Highly accurate circuits are used to generate timebases for instrumentation purposes, usually using a quartz crystal oscillator within a sealed temperature-controlled chamber, known as an oven-controlled crystal oscillator or crystal ...
